OP-50

The ultra-quiet OP-50 preamp features easy-to-use 4-band EQ. By cutting or boosting your guitar’s signal at 87 Hz, 580 Hz, 6.7 kHz, and 12 kHz, you can accurately tailor your sound to any musical environment. Dual XLR and 1/4” output jacks connect the OP-50 to virtually any sound system, stage amp, or recording console, and eliminate the need for an external direct box. Equipped with an easy-to-read LED array, the onboard chromatic tuner works for standard, open, or altered tunings, and can be calibrated to non-standard reference pitches.
